Constant temperature control circuit and method for heat-not-burn cigarettes

Abstract

The invention relates to a constant temperature control circuit and method for heat-not-burn cigarettes and belongs to the technical field of e-cigarettes. The constant temperature control circuit comprises a power source, a startup / sensing control module, a control module, a driving module, a reminding module, and a heater. The startup / sensing control module is used for controlling the power source to power the whole control circuit or not; the control module is used for controlling the selection for a high-voltage constant voltage source module and a low-voltage constant voltage source module in the driving module, and reminding the selection for the modules above through the reminding module; the driving module is used for supplying constant high voltage or low voltage to the heater fordriving and heating the same so that the temperature of the heater rises; the reminding module is used for reminding of the control module's selection for the high-voltage constant voltage source module and the low-voltage constant voltage source module in the driving module. The constant temperature control circuit and method herein have the advantages that temperature control precision and accuracy are improved and temperature uniformity is ensured for smoking.

Description

technical field [0001] The invention relates to a heating and non-combustion electronic cigarette constant temperature control circuit and method, belonging to the technical field of electronic cigarettes. Background technique [0002] With social development and human progress, tobacco, as a harmful consumer product, is gradually replaced by health products with the same function. For example, the recently emerging electronic cigarette products use high-tech means to atomize liquids containing nicotine and other chemical substances to generate smoke to achieve the purpose of smoking. Now there is an electronic cigarette on the market, which does not burn the tobacco, but only keeps the tobacco at a certain temperature, which can bring a smoking experience and effectively reduce the absorption of harmful substances. [0003] The constant control of heating temperature, which has been very common in industrial applications, can achieve the purpose of precisely controlling th...
